LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 422,774, dated March4., 1890.

Application filed July 1, 1889. Serial No. 316,156. (No model.)

To to whom it may concern:

Be it known that I, MADS L. HANSEN, a subject of the King of Denmark,residing at Bridgeport, in the county of Fairfield and State 5 ofConnecticut, have invented certain new and useful Improvements inLasting-Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the IO art to which it appertains to make and use thesame. 7

My invention has for its object to produce a strong, durable, andeasilyoperated machine for lasting shoes which .maybe readily adjustedand adapted to all sizes and classes of shoes, and which will. performthis difficult and expensive operation asneatly and perfectly as it canbe done by hand, in a mere fraction of the time that is required to doit is by hand, and much quicker than it can be performed by any machineheretofore in use.

With these ends in View I have devised the simple and novel constructionof which the following description, in connection with the 2 5accompanying drawings, is a specification, numbers being used to denotethe several parts.

Figure 1 is a side elevation of the machine complete and in operativeposition, the stretch- 1; Fig. i, an opposite side elevation from that i5 in Fig. 1, the last, shoe, and stretcher being removed; Fig. 5, anelevation of the stretcher detached; Fig. (3, a section on the line toa: in

Similar numbers denote the same parts in 3 all the figures of thedrawings.

1 denotes the base of the machine, which is ordinarily a casting madesufficiently heavy to hold the machine firmly in place, and which may,if preferred, be bolted rigidly to the tached; Fig. 8, a detail view,partly in section, illustrating the manner in which the carrier for thelast is raised and lowered; and Fig. 9 I

floor, and 2 is a standard projecting upward therefrom and provided atits upper end with a.reduced threaded portion 3.

4 denotes a carrier for the last, which is pro- 5 5 vided with a centralopening 5, which receives threaded portion 3 of the standard, but is notthreaded to engage therewith, a socket 6,Whieh receives burr 7, threadedto engage the threaded portion of. the standard, and at its lower endwith side pieces 8, which rest against the upper portion of the standardand give stability to the carrier. It will be noticed (see Figs. 1, 4:,and 8) that the opposite sides of the burr project out from the socket,so that the burr may be readily turned to raise and lower the carrier.In the top of the carrier is a pin 9, the lower end of which is threaded(see dotted lines, Fig. 8) to engage the top of the carrier. This pin isadapted to engage a 7c hole ordinarily made in the top of the ankleportion of the last. Should it be desired, however, to operate themachine in connection with lasts not provided with this hole, pin 9 isremoved from the carrier. 5

It will of course be readily understood by those familiar with the artthat when the operation of lasting is performed in the manufacture ofshoes the insole is ordinarily tacked to the last, and the last andinsole are placed within the upper, which is then tacked or oemented tothe insole to hold it securely in place. 7 The shoe is then ready to beplaced in the machine for the operation of lasting.

The last does not appear in the drawings;

but I have shown in Figs. 1, 2, and 3 the bottom of the upper as drawnover the last in the usual manner and as ready to be stretched into itspermanent position by the operation of the machine. go

In use the last, with the insole and upper secured thereto, is placedupon the carrier, as indicated in the drawings, and the sides of theheel of the shoe are grasped by swiveled clamping-plates 10, carried bythe right and 5 ively, by 11 and 12. Both of the holding-arms arebifurcated, the branches thereof being denoted, respectively, by 11" and12. The branches of the right holding arm diverge below the pivotalpoint of the clamping-plate, (see Fig. 1,) and then converge again andter- IOO minate on opposite sides of the standard, as clearly shown inFig. 4. These branches are secured to the standard by a bolt 13, passingthrough holes in said branches and through the standard, and by afinger-bolt 14, also passing through holes in said branches and througha curved slot 15 in the standard, both bolts being provided at theiropposite ends with nuts 16, whereby the parts are held in position afteradjustment. (See Figs.2 and The branches of the left holding-arm(denoted, specifically, by 12) diverge in the same manner as thebranches of the right holdingarm and cross the branches 11 of the rightholding-arm, and then converge again and are united in a shank 17, whichextends downward nearly to the base. (See Figs. 2 and 3.) The functionof this shank will presently be explained. I

l8 denotes an angular supporting-arm, the lower end of which is rivetedfirmly to the back branch of the right holding-arm, and the other end ofwhich curves upward and forward, for a purpose presently to beexplained.

The branches of the holding-arms are pivoted together by back and frontpivots, denoted, respectively, by 19 and 20. The front pivot 20 passesthrough the front branches of the two holding-arms at their point ofinter- The back pivot 19 passes through the back branches of theholding-arms at their point of intersection. Both of said pivots arethreaded at their inner ends and are held in place by nuts 21. At theouter end of pivot 19 is a block 22, which is provided with a transverseopening 23. 7

2& denotes a stud, which is vertically adjustable in the opening in theblock. As

threaded to engage a corresponding thread in opening 23, the height ofthe stud being adjusted by turning it up or down in the opening. It willof course be appare'ntthat if preferred the stud may move freely up anddown in the opening and be locked in position by a setscrew or in anysuitable manner. This, being an obvious mechanical construction, is notdeemed to require illustration. The pivot by Which block 22 is carriedturns freely in the branches, so as to give any required amount ofoscillatory movement to the stud. WVhen the block and stud have beensuitably adjusted, they are locked in position bya setscrew 25, passingthrough the block and engaging the front branch of either of theholding-arms. These holding-arms are operated to cause plates 10 toclamp the heel of the shoe in the manner which I will now describe. Ihave used the terms right and left as applied to the holding-arms toindicate the portion of said arms above the pivots. As the branches ofthe arms cross each other, it

" will be apparent that below the pivotal points the lower end of thearm which I have termed the right holding-arm will be on the left, asseen in Fig. 2, and the lower portion of the shoes are lasted at a time.

A single pivot (denoted by 54) is used tosupport the opposite ends 'of the treadle, and pulley 49, which is shownas recessed into the standard. section, and also through thesupporting-arm. 1

shown in the drawings, this stud is screw- The teeth of these It shouldbe understood that cross-piece 50 and chains 51 are not essentialfeatures of construction, as it is obvious that chain 48 may be extendedupward, pass over a single f pulley socketed in the standard in the samemanner as pulley 49, and the-n connected in i any suitable manner to thetreadle.

I preferably, however, use thecross-piece and the two chains connectedto the treadle, as Ihave found this construction to'work satisfactorilyin use. The forward portion of the shoe is held in position to beoperatedupon by an adjust I able sliding toe-clamp carried by a block37, which slides upon the angular supportingarm. This block is providedwith two or more openings 38, both of which correspond in shape with andare adapted to receive the angular supportingarm. A set screw 39 passesthrough the block and engages the arm to lock the toe-clamp in positionthereon. The clamp proper consists, essentially, of two curved arms 40,which engage the opposite sides of the shoe, as is clearly shown in thedrawings. These arms are carried by upper and lower rods 41 and 42, uponwhich they are adapted to slide. Rod 42 is held rigidly in the block,its ends extending outward therefrom and being engaged by the shanks ofthe right in Fig. 2. The other end of this chain passes partially arounda pulley 49 at the base 1 of the standard, and is connected to acrosspiece 50.

arms. The upper rod 41 is provided with a circular groove 43, whichengaged by a disk 44 upon a right-and-left-threaded screw 45,

said disk also engaging a groove '46 in block 37, whereby all of theparts are held securely in position. The right and leftthreadedportions'of screw pass, respectively, through the shanks of arms 40,each end of said screw being provided with a finger-piece 47 forconvenience in operation. It will be seen that when the screw is rotatedin one direction the arms move away from each other, and when rotated inthe opposite direction they move inward and grasp the shoe firmly, thedisk engaging the grooves in the block and the upper rod acting to holdthe screw and arms central at all times. When it is desired to adjustthe height of the toe clamp, set-screw 39 is loosened, the block removedfrom the supporting arm, and the latter then passed through another ofthe openings in the block. Longitudinal adjustment is secured by slidingthe clamp along the supporting arm. After the clamp has been placed inthe proper position it is locked there by tightening up set-screw "39.As already stated,in' changing from one size of shoes to another-as, forin stance, when used in small shops-the right holding-arm may beadjusted by loosening the nut on finger bolt 14. hen used in largeshops, however, the only movements ordinarily required in removing alasted shoe and placing an unlasted shoe in position tobe op: eratedupon are an upward movement of the treadle to open the clampingarms anda movement of screw 45 to open arms 40. These movements permit thelasted shoe to beread ily removed from the machine. The unlasted shoe,properly secured to the last,vis thenplaced upon the carrier, screw 45tightened to cause the arms of the toe-clamp to engage the forwardportion of the shoe, and the treadle pressed downward to cause the heelof the shoe to be firmly grasped by the clampingplates. The treadle isthen looked in position by engagement with one of the racks.

The lasting of a shoe is performed in the manner which I will-nowdescribe. At the upper end of stud 24 is pivoted the stretcherrod 26,upon which the stretcher 27is adapted to slide. This rod is providedwith circular depressions 28, adapted to be engaged by a pin 29,projecting inward from a lever 31, pivoted to the outer side of a sleeve30, to which the stretcher is pivoted, so as to oscillate freely. Theinner end of the pin passes through a hole in the sleeve and is held inengagement with one of the circular depressions by a spring 32. When itis desired to adjust the sleeve longitudinally, the rear end of thelever is pressed down, which raises the pin and allows the sleeve toslide upon the stretcher-rod. The instant the lever is released thespring acts to force the pin into engagement with one of the circulardepressions in the strcteher rodand locks the stretcher againstlongitudinal movement. In use it should be unden stood that the sleeveand stretcher turn freely justment of the rest, should it be required,

the shank thereof is provided with two or more angular openings 35,corresponding in shape with the angular supportingarm, either of whichis adapted to receive said arm. The rest is locked in position, afteradjustment as to height, by a set-screw 36, which passes through theshank of the rest and engages the supporting-arm. The stretcher consistsof upper and lower jaws, (denoted, respectively, by and 57.) These jawsare pivotedtogether, as at 58. At the rear end of thelower jaw is ablock 57 having in its under side ways 59, which are engaged bycarrier-block 60, which in turn is connected to block 30 by a pivot 61,which permits the entire stretcher to oscillate freely on the sleeve. Atthe rear end of the carrier-block is a stump 62, whichis threaded toreceive a screw 63, the outer end of which is provided with'a crank 64forconvenience in operation, and the forward portion of which is reducedand passes through the block at the 'rear end of the lower jaw. Thereduced portion of the screw is provided with a groove,'which is engagedby pins 65, driven through block 57, and engaging the groove.

(See dotted lines in Fig. 5.) It will be seen,

therefore, that as the screw is held against longitudinal movement inblock 57 and engages a corresponding thread in stump 62, the stumpitself being held against longitudinal'inovement by being locked to thestretcher-rod, when the screw is rotated, both jaws are necessarilymoved either forward or backward. rated in the usual manner, so as togive a firm hold upon the upper, which is caused to be firmly clamped bya screw 66, which passes through the upper jaw and engages block 57 uponthe lower jaw. This screwis The jaws are preferably serprovided with acrank 67 for convenience in operation. 68 denotes alifter,whichconsists, essentially, of a cross-piece '68, which may, ifpreferred, be provided with a roller and arms 68", one only being shown.These arms are riveted to the ends of the cross-piece andlie on oppositesides of the lower jaw, their rear ends being pivoted to the arms of abifurcated lever 69, saidlever being pivoted to block 57, as at 70, andits oscillation lim ited by pins 71 in block 57. d

T to operation of stretching the upper over the bottom of thelast---that is, the operation of lasting proper--is performed asfollows: The shoe is placed in the machine in the manner alreadydescribed, the forward portion of the shoe being caused to be grasped bythe toe-clamp by rotation of screw 45, and the heel portion of the shoebeing clamped between plates 10 by pressing the treadl'e downward. Thestretcher rod, with the stretcher upon it, is placed in proper positionto permit the engagement of the upper by the jaws of the stretcher, theforward end of said rod being supported by the rest, as alreadyexplained. in the open position, the upper and lining are placed betweenthem and screw 66 rotated in the proper direction to clamp the upper andlining firmly between the jaws. Screw 62 is then rotated in the properdirection to move the jaws backward, stretching the upper into position.In certain portions of the shoe as, for instance, in stretching theupper over the widest portion of the lastinstead of having the entirestrain upon the upper in the backward direction it, is desired to havethe strain upward from the bottom of the last. This result isaccomplished by pressing lever 69 downward-that is, toward the left, asseen in Fig. 2. This forces the cross-piece forward between the insoleand the lower jaw, raising the jaws and causing the strain upon theupper to be upward and backward instead of directly backward, as whenthe lifter is not used. It will be seen that anydesiredamount of strainmay be placed upon the upper. As each portion is stretched it is securedin place in any suitable manner, ordinarily by short tacks driventhrough the upper and the insole. As soon as the stretched portion ofthe upper has been secured in place the upper is released by looseningscrews 63 and 66. The stretcher may then be moved forward or backward onthe stretcher-rod by releasing the pin on the sleeve from engagementwith one of thecircular depressions in the rod. If it is desired tostretch a portion of the upper upon the opposite side, the position ofthe stretcher-rod is shifted in the rest. is desired to change theposition of the rear end of the stretcher-rod, block 22 is oscillatedmore or less, as may be required. It will be seen that I am thus enabledto place the stretcher in any position where it can possibly berequired, that the upper is gripped by the movement of a single screw,and that the stretching operation is performed by the operation ofanother screw, assisted, if required, by the movement of the levercontrolling the lifter- Should it be desired at any time, the ma chinemay be used in any of the other operations in manufacturing shoes-as,for example, in stitching, soling, nailing, &c.without change, as ajack, the shoe being held by the toe-clamp and clamping-plates in themanner already fully described.
